1'0 all whom it may concern:

Be it known that I, EDWlN L. Gees, a citizenof the United States, and a residentof 'l-oledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Collapsible. Drum for Veneer-Package Machines; and I do hereby declare the following to be a full, clear, and exact dcscrip lion of the invention, such as will enable others skilled iu'the art'to which it apperiaius to make and use the same, reference being; had to the accompanying drawings, a ml to the figures of reference marked there on, which form a part of this specification.

My invention relates to package forming machines, and particularly to the class of such machines in which veneering or other like material is shaped in cylindrical. form about a forming drum or mandrel.

The primary object of my invention is the provision in u machine of this class of an improved form of forming drum or mendrel, the segments of which are each mounted for contractual or collapsible movements relative to the drum axis, whereby circumferential 'rooves in the drum in which the internal noops or strengthening means of the barrel or package seat are drawn inwardly free from such hoops or means to permit on easy and unrestrictedwithdrawal of the formed article from the drum.

' The operation, construction and arran' cment of the parts of the invention are fully described in the following specification and illustrated in the accompanying drawings, in which," 1 I Figure 1 is a front elevation of a machine embodying the features of my invention with one end portion of the-forming drum in section. Fig. 2 is an enlarged cross-section of the drum on the dotted line as w in Fig. l, and Fig. 3 is a similar section with the parts shown in collapsed position.

Referring to the drawings, 1 designates the drum-shaft, which is shown as having one end journaleol in the two bearing-standards 2, 2 and its other supported in a bean lug-gate 3, which is hinged in a suitable manner to one of the standards 4 of the machine The standards 4 are disposed at suitable distance to the rear of the shaft 1 to permit an endwise removal of the formed article from the shaft-drum when the gate 3 is sw ung outwardly for such purpose.

Mounted on the shaft 1 between the etc 3 and inner standard 2 is the collapsible forming-drum or mandrel 5, the shell of which is composed of a plurality of segmental sections 6, which, when lying with their side edges abutting, are intended to form a true cylindrical surface, as shown in Figs.

'1 and 2. Projecting inwardly from the end erably disposed in tangential relation to the shaft 1 so as to exten point of connection shown;

interposed between the two end collars 10 of the drum on the shaft 1 therewith is a sleeve 11 which has its ends shutting against said collars and provided with radial arms 12. These arms correspond in number to the drum segments and are provided at their ends with lateral studs 13, which Work in cam slots let providedlongitudinallyin the contiguous segment arms 7 adjacent their outer ends, as shown. It is thus apparent that a. relative turning in one direction of the collars 10'andsleeve 11 when the segmentsare in expanded or setup position, as in Fig. 2, will cause the studs 13 to move laterally from their with the arms 9 as outwardly in their respective slots 14 and efi'ect a simultaneous and uniform collapsing or contractual movement of all of the segments relative to the drum axis due to the segments oscillating in the same direction on their pivots 8; and that a relativeturning in the other direction of said sleeve and collars when the parts are in colla used position, asin Fig. 3, will cause the stu l3 to'move inwardly in their respective slots and efiecta simultaneous and uniform outward movement of the segments on their pivots'to setup position. In order to reduce the triotional resistance between the studs 13 and slots 14 when the collars l0 and sleeve 11 are relatively turned, the arms 12 are curved in the same direction in which the attached segment-arms 7 extend from the arms 9 of their collars so that the arms '12 and the respective slots 14 in which they work stand in substantial longitudinal alinement;

The parts of the drum are locked in set-up or expanded position by threadin an armnut 15 to an extended end of one o the studs 13 ofi lhecrms 12, thus adapting a tightening movement of the nut to clamp the associated arms 7 and 12 together, or this locking may be accomplished in any other suitable or convenient manner. The armonut 15 also serves as a handle which the operator can grasp and turn with the associated arm 12 and its sleeve when it is desired to impart relative rotation to the collars l0 and said sleeve for the purpose of collapsing or expanding the 1: drum parts. For this reason the sleeve 11 is shown as being loose and the collars fixed to the shaft. As the swinging movement of the segments when being collapsed causes the forward edge of each to work within. and

15 past the rearedge of the next section, as shown in Fig. 3, the abutting edges of the segments are oppositely beveled in a manner to permit of such movement, as shown at 16.

To adapt the drum for the forming of barrels or like packages having internal hoops or strengthening pieces, it is provided with a desired number of circumferential grooves 17 in which the hoops or strengthening pieces may lie during the forming process as hereinafter described.

-Power is communicated to the drum-shaft bya belt engaging the pulley 18 on the shaft 19, which has one end journaled in a pivotalbearing carried by one of the standards and its other end carrying a frictioirwheel 20 for coaction with the friction wheel 21 to transmit rotation to the shaft 22, which in turn transmit rotation to the drunrshat't throu h the medium of thespur-gears 23.

The trictionovheels 20 is thrown into engagement with its companion by a lowering of the foot-treadle 24, which is t'ulcrumed to the frame base, as at 25, and has its short arm connected to the shaft 19 in a suitable 40 manner to effect a raising of the wheel when the other end of the treadle is lowered.

The pressure-roller 26, which holds the veneering to the drum'as it is being wound thereon, has its ends connected to the cross head 27, by which it is carried and which is mounted tor Vertical movement in suitable guides in-the members l, i. To facilitate a raising of the roller 26 from engagement with the drum, a link 28 connects the crosshead with an overhead lever 29, which is fulcrumed to the frame top in a suitable manner and has its handle end adapted to engage a toothed arm 30 on the frame to retain it in adjusted position. 31 designates the usual guides through which the outer hoops of a double veneer barrel or package pass they wind on the drum with the veneering.

In the making of double veneer-packages. the internal hoops are fed to the grooves 1'7 6 of the drum and the layers of veneering are fed between the drum and the pressure-roller 26, and their forward ends secured to the drum by being clamped between the abutting edges of two segmental sections 6 of the drum, or secured thereto in any other suitable mannei. Shouhil external hoops be also used they are passed through the quidcs 31 and between the pressure-roller and layers 0': veneering in the same manner as in the machines heretofore employed for such purpose. l Vhile the venccring and slrcnglheir mg hoops are being ted the drum will be caused. to slowly revolve by a downward pressure on the lrcadle 24- to throw the wheels 20 and 21 into frictional engagement. As soon as a suliicicnl length ol? vcnccriug has passed the pressure-roller 26 the llcndlc 24 is released. and the drum stops. The meeting ends of the vencering and hoops are now secured together in a. suitable manner and the barrel or other package is ready to be removed from the drum. To accomplish this, the gate 3 is swung free from the shaft end, the arm-nut 17 turned to release the clamping action of the associated scgjnucul and sleeve arms 7 and 12, and the sleeve ll and its arms then thrown in the proper di rcction relative to the shaft to cause the studs 13 to move outwardly in their respective slots Ll and etlcct a suliicicnt contractual or collapsing movement of all oi the drum sea ments to withdraw the grooves 17 l'rom cugagcnicnt'vvith the internal hoops ol the formed article, thus permitting the article to be l'reely withdrawn from th drum lengthwise thereof.

I wish it understood that 1 do not dcsirc to be restricted to the cxacl d tails of con struction or arrangement of the parts shown and described, as obvious modifications will occur to persons skilled in the art.
